Jira trigger transition if pull request created (or update) and doesn't contain the word "WIP"

[danprinz]

Hi.

I want to automatically transition an issue from "In progress" to "Review" whenever a pull request is created. this is perfectly supported by Jira. 

But I want to add a condition such as if the pull request contains the word "WIP" (Work In Progress"), the transition will not take effect. It happens that a developer want to open a pull request which is still not completed, in this case the issue is still "In progress" until the "WIP" will be removed.

Is it possible?
